"may last millions of years, or may last only a fraction of a second" I love that sentence, and I really hope we develop experiments to narrow that down a bit.
9:46 i like these subtitles, because sometimes I forget what was just said or exactly what was meant by it and now I can see it right there. very nice
Just read a book on neutron star coalescence and how they are the factory of a large portion of the heavy elements found in the universe through nucleosythesis. Such an interesting read !
8:40 that simulation is WILD 🤩
If the axion cloud collapse is the source of FRB's, wouldn't that imply that FRB's are omnidirectional? If so, there should be cases where we might be able to detect reflections. The time between the initial FRB and reflections might be long, but information about the universe that could be extracted by analyzing them could be game-changing.
Those helical fields look pretty cool
It's like I'm sitting at the front of the classroom
A huge thank you to you Matt and to the whole Space Time team for making appreciation of reality (with sources) so accessible to us lay persons. Much appriciated! Another well made vid. cheers! :)
@13:33 "Them Neutron Stars" sounds like a future Country-Western song title. "I've been to Memphis bars and lived through countless spars Was nearly sent to Mars by a Nordic dude named Lars I've driven loads of cars and earned my share of scars But she confused me up and down just like them neutron stars" (Note: I am not from the South, but I tried)
I first heard about Neutron Stars when I read the eponymous short story by Larry Niven. An interest in nerdy sci-fi has got to be good for something.
Robert Klauber's "Student Friendly Quantum Field Theory, Vol 2" has a great discussion of axions and CP violation. He's written the most understandable textbooks on QFT that I've found.
Finally some movement on the origin of dark matter and possibly an explanation for FRBs... exciting!
The fact that I (as I'm sure many others) understand this video with complete ease is a testament to the excellent long-term educational service you folks are providing. Love sitting at the front of this grad school classroom over the years!
4:35 love the Axion logo!
Loved the Axion detergent logo showing up in the animation!
Can y'all bring back questions? I loved them.
The people who comes up with that math for this are crazy but the people who code the animations and ability to show it are Insane
this dark matter info will immensely help my cloned neanderthal starship captain on a galactic voyage i'm writing about.
So this sounds interesting, but color me skeptical. Haven't we been predicting the existence of axions for decades & we keep not finding them & keep revising our models that predict them & then we keep not finding them?
